Routines for gridding LineP data.
These routines make netcdf files that are organized by depth, cruise number, and station for the nominal Line-P stations. Data starts in 1968.
A CTD cast is considered at a LineP station if it is within 7.2 nm of the nominal station location.
A cruise is considered a LineP cruise if it has at least four occupied stations, and it made it as far offshore as P10.
wget -i LineP/wget_netcdf_file_download_list.csv
to download all the data from waterproerties.ca. Note you may need an account to access this data.
To get this list, go to https://www.waterproperties.ca/data/
and search the map under "Defined Area": "Line P", and then file suffix "ctd", and then under "Download": "WGET netCDF"
